摘要
LNG接收站涉及天然气甲类危险介质,根据国内外项目经验,一旦发生火灾会造成严重后果。基于此,接收站内地上相关设施,例如:压力容器、钢结构、消防管道等,都需要仔细考虑防火设计。本文通过分析LNG接收站地上设施的防火措施,为其他类似项目的防火设计提供借鉴。文章分别从主动防火、被动防火两个方面对防火设计进行深入分析与介绍,包括:消防系统、消防水泵联动逻辑、消防炮选型原理,以及安全阀火灾工况、防火材料等。同时,针对防火材料认证问题,与国外项目方案进行了比较,结合工程经验,从第三方认证的角度,着重介绍了个人观点,也对目前的认证流程提出了建议,为后续同类项目提供参考。
LNG terminal involves Class A hazardous medium of natural gas,and according to the experience of domestic and foreign projects,once a fire occurs,it will cause serious consequences.Based on this,the relevant facilities on the ground of the terminal,such as pressure vessels,steel structures,fire pipes,etc.,need to be carefully considered for fire protection design.This paper provides reference for fire prevention design of other similar projects by analyzing the fire prevention measures of above ground facilities in LNG terminals.The paper provides an in-depth analysis and introduction to fire prevention design from two aspects:active fire prevention and passive fire prevention,including fire protection systems,linkage logic of fire water pumps,selection principles of fire monitors,as well as fire conditions of safety valves and fire prevention materials.At the same time,regarding the certification of fire-resistant materials,a comparison is made with foreign project schemes,combined with engineering experience,and from the perspective of third party certification,this paper focuses on personal views.Suggestions are also put forward for the current certification process,providing reference for similar projects in the future.
